Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. A paper on the work is published in Nature. —Donald Sadoway.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) The compressed air, now cool and easier to store, is housed in a large air tank.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The California-based Hyperlight Energy will be piloting an installation where they plan to use existing oil wells as solar thermal wellsprings, with the stored energy being converted back to clean electricity when required. A possible answer, though, might lie in oil wells. to test the concept for the first time.

There’s another benefit to this battery, and this one will make EV drivers very happy: It will take only 10 minutes to reach an 80 percent charge in EVs powered by these batteries, Rustomji estimates. The rare earth oxide then undergoes a molten-salt electrolysis process that converts it into a solid metal form.

What is Home energy management system, why it is needed

Baua Electric

Because they usually sit for a long period of time, their charging can be shifted to periods when either solar generation is high or electricity prices are low. Energy Storage Systems Batteries or other storage systems can be integrated into a HEMS to store excess energy during periods of low demand and release it during peak demand times.

New $30M ARPA-E program to develop new solar conversion and storage technologies; targeting higher solar penetration in mix

Green Car Congress

Penetration of PV will ultimately be limited unless breakthrough technologies enable hours of electricity generated by PV to be cost-effectively stored. The marginal economic value of installing PV is predicted to fall by half when PV meets more than 20% of the California utility load. Charge and discharge time of storage.
